The way I see it your Content-Length is wrong - the
length of your request in this instance would 380 bytes,
based on the length of $xmlstr. but that's probably not right
either.
I imagine you need to set Content-Length dynamically,
assuming curl doesn't do that for you ...
as a side note: why bother setting all these vars then stricking
them in an array - why not just stick the strings directly in the array?
additionally if you don't need to use double quotes (for variable
interpolation) single quotes are [marginally] faster [in theory] because
no variable interpolation is attempted on them.
e.g.
$headers = array(
'Accept-Encoding: gzip',
'Transfer-Encoding: identity',
'Accessmode: agency',
'Accessid: XXXXXXX XXXXXXX_layout',
'Accept: application/xml',
// etc
);
> $a_encoding = "Accept-Encoding: gzip";
not related to your current issue, but are your really accepting
a gzip'ed reply? this might cause you headaches once you have the
current problem solved.

I am guessing that the urlencoded $xmlstr should be given a POST parameter name,
what that name is I don't know but the previous line should look something like
this (*I think*):
curl_setopt($curl, CURLOPT_POSTFIELDS, array('xml' => urlencode($xmlstr)));
you might consider point the curl request to a script you control,
so that you can see exactly what the request is sending.
e.g. $url = 'http://yourdomain.tld/your-curl-request-test.php';
... and have your-curl-request-test.php write all it's recieved headers, etc
to a log file.
